Paper sheet separation/conveyance roller

Abstract

A paper-sheet-separating/conveying roller 10 includes a rubber member (conveying member 11 A or 11 B) having a specific diameter and a through-hole at the center thereof; a core (protrusion 12 b or 12 c ) inserted in the through-hole; and supports which have a diameter greater than that of the core and smaller than that of the rubber member and which sandwich the rubber member from both sides, wherein a member (fixing member 12 ) having the support which is in close contact with one side surface of the rubber member and a member (holding member 13 ) having the support which is in close contact with the other side surface of the rubber member are aligned and fixed in an axial direction.

1 - 6 . (canceled) 
     
     
         7 . A paper-sheet-separating/conveying roller characterized by comprising:
 a rubber member having a specific diameter and a through-hole at the center thereof;   a core provided in the through-hole; and   supports which have a diameter greater than that of the core and smaller than that of the rubber member and which sandwich the rubber member from both sides, wherein a member having the support which is in close contact with one side surface of the rubber member and a member having the support which is in close contact with the other side surface of the rubber member are aligned and fixed in an axial direction.   
     
     
         8 . A paper-sheet-separating/conveying roller according to  claim 7 , wherein the area of a portion of each side surface of the rubber member, the portion being covered with the corresponding support, is 27% or more of the entire area of the side surface. 
     
     
         9 . A paper-sheet-separating/conveying roller according to  claim 7 , wherein the supports and the core are formed of a metal or a resin. 
     
     
         10 . A paper-sheet-separating/conveying roller according to  claim 7 , wherein, in the rubber member, the ratio of thickness T 1  as measured in a radial direction to width W 1  as measured in an axial direction, represented by T 1 /W 1 , is 0.5 to 2.3. 
     
     
         11 . A paper-sheet-separating/conveying roller according to  claim 7 , wherein the rubber member exhibits a percent expansion of 0 to 7%. 
     
     
         12 . A paper-sheet-separating/conveying roller according to  claim 7 , wherein the rubber member exhibits a percent compression of 0 to 13%.
